Motor Data
Identification
Failure
Motor data identification failed.
Alarm value =0: Load missing
Alarm value =1: Current limit level
reached during identification.
Alarm value =2: Identified stator
resistance less than 0.1% or
greater than 100%.
Alarm value =3: Identified
rotorresistance less than 0.1% or
greater than 100%.
Alarm value =4: Identified stator
reactance less than 50% and
greater than 500%
Alarm value =5: Identified main
reactance less than 50% and
greater than 500%
Alarm value =6: Identified rotor time
constant less than 10ms or
greater than 5s
Alarm value =7: Identified total
leakage reactance less than 5%
and greater than 50%
Alarm value =8: Identified stator
leakage reactance less than 25%
and greater than 250%
Alarm value =9: Identified rotor
leakage inductance less than
25% and greater than 250%
Alarm value = 20: Identified IGBT on-
voltage less than 0.5 or greater
than 10V
Alarm value = 30: Current controller
at voltage limit
Alarm value = 40: Inconsistence of
identified data set, at least one
identification failed
Percentage values based on the
impedance Zb = Vmot,nom / sqrt(3) /
Imot,nom
0: Check that the motor is connected to the
inverter.
1-40: Check if motor data in P304-311 are correct.
Check what type of motor wiring is required (star,
delta).
